FUS1 - protein with SH3 domain required for cell fusion during mating, located at the tip of the mating projection

BNI1/YNL271C (Saccharomyces cerevisiae)

Formin, nucleates the formation of linear actin filaments, involved in cell processes such as budding and mitotic spindle orientation which require the formation of polarized actin cables, functionally redundant with BNR1
